v0.6.5

Fixed: popup title.
Not fixed: AV1 thumbnails won't work yet. The technical reason is that the ffmpeg bulid I am using doesn't support AV1 yet (vcpkg) and I don't want to change to build it myself at the moment.

This release has experimental and bad support for non-local files.
- Live streams will still not synchronise properly, fixing this is still not simple.
- You can enable it for foo_youtube items or any non-local item in Advanced Preferences->Playback->mpv. You can use the option 'Ignore filter query' so that it will try to play every non-local file, ignoring the "Only play files matching" option.
- You must place youtube-dl.exe into <foobar profile>/mpv. I don't think there is any way to tell mpv where to look for youtube-dl so I don't think I can point it at a global youtube-dl install. You could try symlinking it to another place maybe. I expect it works if youtube-dl is in your %PATH%
- You don't really get any visual feedback yet about what mpv is doing when loading youtube-dl, and nothing much in the Console, so it might be confusing why it isn't working. You should be able to tell from mpv.log afterwards.
- At least for me, it doesn't work in Linux/Wine. The libmpv thread loading youtube-dl just freezes and the player will stop working and need to be killed. It also doesn't work in standalone mpv so might not be easily fixable. If it does work for you please let me know!
- It will still use the same aggressive logic to synchronise audio/video, with no clever handling of slow network conditions. This works very well on Youtube for example, with fast enough internet, but if the video won't download fast enough you could get messed up playback as the component constantly tries to fix video sync but the network can't catch up. By default it will start loading the video 4 seconds after the current playback time to give some time for the file to start downloading. You can change this in advanced preferences.
- If you have foo_youtube video player also visible, or foo_youtube is somehow set to download the video, you will be downloading the video stream twice. For some sites, where the website only streams audio+video together, you might always be downloading the audio and video twice, which is pretty bad, it's just a limitation of the simple way this is implemented.

@sammoth,
Thanks for your responsiveness to users and trying to implement streaming video playback.
Playing YouTube clips works pretty well.
Currently, the highest quality YouTube video is selected for playback by default. This has a limitation on slow computers.
It might be sufficient to add a youtube-dl configuration window, similar to the mpv.conf and input.conf windows. In which the user can set the video resolution and codec.
HLS streams in my playlist are played but not synchronized.

mpv is handling launching youtube-dl, so its options for quality should work, see here and here (yes it's kind of complicated). Note that you probably want to use strings that just match video streams.

For example for playing 720p only put in mpv.conf

Code: [Select]
ytdl-format="bestvideo[height=720]"

Thanks, this tip helped.
Is it possible to set only a specific codec to play YouTube videos, for example, only H264?
since my computer does not play vp9 video codec properly.

Maybe try
Code: [Select]
bestvideo[height<=720][vcodec*=avc]

Hi.  Would it be feasible to have MPV automatically pop up when a video is played?  I suspect this would take more effort than it is worth, but decided to ask anyway just in case you thought it might be worthwhile.  Thank you again for this great component.

Seems possible. Pop up automatically when there is video to play and disappear when there isn't? It would make most sense to have a menu entry to toggle it as I guess you would only want it on sometimes.

What you described is exactly how the youtube video player works and the only feature I miss since switching over to MPV.  It would be a nice to have if you can find the time and hopefully something others would find useful.
